If you know how to use an oscilloscope, this shouldn't be too hard to figure out. There are somethings that it takes a moment to figure out, like that the V and mV button don't mean "Volts" and "millivolts", but they mean "increase voltage scale" and "decrease voltage scale".It comes with a probe set with clips on the end, and a probe set that has one clip and a hooked probe with a 1X/10X switch. Using the probe with the 10X switch on this will measure up to 400V, so you can check your power line waveform. I've also used it to check output to a stepper motor and it showed the not-quite square wave I was expecting. The device also has a square wave generator that came in handy for testing some functions. The auto scaling feature worked okay in some cases, but not all.For an inexpensive scope in this frequency range, I think this is a good deal.

500ms/s may be true, but the built in screen refresh rate is around 15hz or so. As the amplitude or frequency changes, the displayed transition is not very smooth. Display is bright and surprisingly legible, even while outside. Battery life is about 3.5hour on a full charge. Triggering isn't the best but it is usable. Not a pro level scope by any means. For this price, this is great for learners and DIY/hobbyist!

The last time I used an oscilloscope in anger it had a CRT display and valves inside it. I'm not any kind of Electronic Engineer, but I do enjoy tinkering with Arduinos and other microcontrollers.I found the ANKONG 1C15 to be a good match for my skill level and needs. I tested it on two Arduino generated signals that are fairly typical of the kind of thing I want to capture. One picture shows an IR control signal with a 560uS pulse width (say 2kHz), the other shows an Adafruit Neopixel control signal at 800kHz. In each case the "AUTO" button on the device did all the hard work for me and captured the waveform.The oscilloscope and accessories are of good quality, though the included USB power adapter has European style round pins. (Not a problem for Arduino tinkerers.)A welcome addition to my workbench.
